Oriental Motor USA is pleased to announce the introduction of our new RKII Series 0.72° stepper motor and driver packages which are the successors of our existing popular RK Series AC-input motor and driver packages. The RKII Series offers even greater performance and features with a price savings of 7 ~ 28% compared to the original RK Series. The New RKII Series is an ideal and affordable solution for open loop requirements and is available with a built-in controller (stored data) type driver or pulse input type driver for the same price.

DIFFERENCES & IMPROVEMENTS:The original RK Series was one of our most popular packages and with its’ full product breath of various gears and input voltages. It met the demands of customers from Packaging, Semiconductor to Vending applications. The RKII Series was developed to be an even more compact and affordable product than our original RK series with higher efficiency characteristics which reduce motor temperature (up to 40 deg C less) and save energy consumption (up to 47% less) along with being much simpler to wire and program. We were also able to make the drivers smaller by optimizing the driver design. With the adoption of the step angle selector, now common on all of our 0.72° Stepper Motor packages, switching to and from 1.8° or 0.9° resolution is as simple as setting a dial. To meet more demanding requirements, the RKII Series is also equipped with an Electromagnetic Brake option and offers increased torque, speed range, and lower backlash on our latest Planetary, Spur, and Harmonic gearheads. The RKII Series was designed to be our new open-loop standard in Stepper Motor and Driver packages providing advanced performance at OEM prices.
